Lasker Trap

'''Introduction to the Work: Yoon Su-hyun, ace of the Vampire Hunter Agency. Due to trauma from an accident in childhood, Su-hyun struggles to trust people, not only drifting apart within the team but also being avoided by his teammates themselves. "We meet again, huh." Then one day, a man who shared a night with Su-hyun—who stubbornly believes in the principle of not sleeping with someone twice after doing it once—joins the Alpha Team as his junior. And they even have to live together under the same roof?'''
